I'm 36, been smoking for about 20 years, but i am about to take the plunge and try to make the big switch! At my worst, i was near 4 packs a day, at my best, I've been down to 7 cigs a day with a nicotrol inhaler, but I missed seeing the smoke come out, so i am back up around 14 smokes a day right now. Looking forward to the future!
